Our Technical Department can offer advice on appropriate styles of Rootline for differing situations and on typical installation details. Using Rootline prevents the lateral spread of roots, deflecting them harmlessly down into the ground allowing healthy growth, but mitigating damage to the structure. This is fine, unless the root growth is beneath or adjacent to structures where it may cause significant damage. Normal, healthy root structure growth occurs laterally through the upper surfaces of the soil.

Rootline GHD100S3 is water impermeable HDPE with a 3mm pocketed surface.

Rootline GHDR 85, 120 and 200 are water impermeable HDPE with a plain surface.

Rootline is available in the following formats: A root barrier is usually installed between concrete foundations or flatwork and adjacent trees within their mature height from the foundation and where. Impermeable Rootline is preferred for most situations and the plain version is the most economic, but the dimpled and pocketed version of Rootline is the most effective in vertical applications, guiding the roots into a downward direction. Rootline is available in two styles of robust flexible polymer (PP or HDPE) sheets that resist penetration by roots. The primary root barrier categories include mechanical root protection barriers and chemical tree root inhibitors.

Rootline root control barrier can be installed around the tree or adjacent to the structure or wrapped around pipes etc. A root barrier should be considered only when it has been clearly demonstrated either that tree roots have contributed to damage, or that there is a real risk. A good root system is essential to sustain healthy tree growth, but the roots can be deflected to grow downwards and avoid damage to adjacent structures or services.

Tree roots predominantly grow in the upper surface of the soil and spread out extensively and laterally from the trunk.
